Abstract |
This paper presents a new method of theoretical modelling of strength effects and strains, which have a crucial influence on the deflection of steel beams in fire. This method is based on a new model of steel creep at elevated temperatures and the modified Ramberg-Osgood equation. The analysis of the deflection of beams in fire was based on the Mohr's integral generalized over non-elastic materials. With the help of the equations introduced in the work it is possible to generalize and to foresee, with high accuracy, the results of rather expensive fire endurance tests of steel beams. |
